This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of.... -
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is.... -
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to.... -
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This.... -
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the.... -
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,.... -
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the.... -
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power.... -
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....

The most amazing thing about this project is the small number of parts. My boss joked that it...
Normally analogue-to-digital con-verter (ADC) needs interfacing through a microprocessor to...
This logic probe has four channels and uses two IF quad comparators to drive four bicolor LEDs....
If you are busy and cannot answer or do not wish to answer your phone, this circuit will give a...
To order boards, click to go to the ESP Purchase form. Verify the price and postage, then open...
This circuit, enclosed in a small plastic box, can be placed into a bag or handbag. A small...
The Network Time Protocol (NTP) has revolutionized the world. Suddenly one could have anywhere in...
It can detect what`s being typed on it. It can be used to send text to and/or receive text from a...
This machine`s playfield features a catapult that fires the pinball, trolls that pop up from the...
To design and build a wireless transmitter that works over the FM frequency and allows the...
3130 CMOS opamp gives required high input impedance for pH probe at low cost. Output of probe,...
The device uses a microammeter with full scale deflection of 50 uA and with the resistance of 2...
M5227P is the application circuit, for graphic equalizer, its control curve is always logarithmic...
Cheap I2c shown as a bus control stereo decoder TDA9853H. Used for a digital mediation function...
